Line-us is by far the cutest drawing robot we've ever seen.
Currently raising funds on Kickstarter, this little bot is essentially a USB-powered arm that connects to an app on your tablet or smartphone and copies anything you draw in real time. (The software also works on Macs and PCs.) You can use it to just play around by mimicking your doodles, or connect it to the internet via Wi-Fi and send and receive messages from anywhere in the world. If someone has the app, they can send a drawing straight to your Line-us over the internet. Okay, so it's hardly a practical way to get in touch with someone, but who cares: it's got personality.
